Comp Sci Computional Methods Problem with Fortran programming

[kevek]

Is there anyone familiar with Fortran programming, who can give me some simple ideas or resources how can I strart this project? Many thanks


Data Structures - The Permutation Group
In this project, the group of permutations on N elements (where N is probably fairly small, perhaps N= 9 or less) is represented as a data structure. The main program employs the USE command to access a module containing the declarations, type definitions, functions and subroutines.
The module should use operator overloading to make * the multiplication operator between permutations, and ** a permutation taken to some ower. The module should also have a function or subroutine that determines the order of the permutation.

Options
1. Create a subroutine that inverts a permutation.
2. Create a subroutine that converts a permutation to cycle notation.
3. Create a subroutine that determines whether a permutation is even or odd.
4. Discuss how other algebraic structures could be represented and calculated.

First thing to do is to write a simple permutation function that performs the correct results on 123. Also, use C++ not FORTRAN.

Try this reference it might help.
